My invention relates to improvements in vehiclespi'iiig shackles used in connecting the eye formed ends of vehicle chassis and spring members, the improved shackle being particularly designed and adapted to automatically take up wear and prevent looseness between the edges `of the eyeA formed Y, j spring members, or thehangers forthev lati0 ter, and consequently preventing any noise portions. of vehicle chassis and or rattle between adjacent parts.` l y r,he primary object of the invention is to provide a generally improved vehicle spring shackle of the type ivill be exceedingly cheap of manufacture, and elcient in use.

A the provision ofan improved shackle adjusting and fastening device which may be read ily att-ached to or detached from the threadediend of an ordinary shackle bolt `Without the removal of the latter and consequently LWithout in any kway disturbing or disconnecting the adjacent parts.-

A further and importantobject is the pro-. vision of an improved shackle bolt adjusting and fastening device comprising an improved iiut adapted to be used in lieu of the ordinary nutv on such shackle bolt,` together or class indicated, which with a compression device surrounding said .j nut and controlled and asembled by the latter and excluding dust from the adjacent threaded and other portions. j

' `With the above mentioned and other ends in view, the invention consists in the novel construction, arrangement, and combination of parts, hereinafter one of its embodiments in the accompanying drawings, and particularly pointed out in the appended claims.

Referring' to the drawings forming a part of this specification, Figure l is a side elevation of a vehicle chassis side barand spring member embodying a shackle connection arranged and constructed in accordance With this invention.

Fig. 2, an enlarged view of the improved spring' shackle, partly in elevation and partly in section, taken on line 2 2 of Fig. l.

Similar numerals of reference designatel like parts throughout drawings. j l

The vehicle chassis frame member l, and the vehicle spring member 2, may be of any suitable and convenient construction and all the figures of the relativey arrangement, and forming no specific part of the present shown and the further andvvery important object'is.

it Will be seen that I provide a protect the threaded end l"` .receive and be described, illustrated in y invention, the saine neednot be describedin detail. l

For the purpose of illustra-tion I have j my improved shackle in connection with the ye formed or curved or olli-set end of a chassis side eye or loop 2,"oll a spring of the leaf type.. j Y

The shackle links 3 and shackle bolts l may likewise be of any suitable and conveiiient form or type. In the present instance, I have shown the bolts 4 with suitable lubricant `carrying and feeding ports and provided With the usual tubular bushings an. simple in construction,

rIhe shacklebolts 4- are providedv with threaded endslll,` projecting from oneside `of one of the shackle links 3, as shown.

Referring noiv to the improved shackle link vandbolt adjusting and tensioning device to which this invention particularly relates, of nut of the type generally Vknown fas blind nuts, for use inI lieu of the ordinary nut now commonly employed. The nut is kprovided on its inner or underside with a threaded opening or bore 524m the cy# lindrical section 5, adaptedto.surround and of the bolt, said cylindrical section 5 terminating at its outer l end inan enlarged adjusting head 5b, of any suitable convenient angular former type to moved by a suitable Wrench. As a meansof resiliency and frictionally clamping Athe eye -or loop ends la and 2% of the connected vehicle and spring members between the shackle links Sto take and prevent rattle between the connected parts, the nut 5 is provided with a suitable compression device interposed between one of the shackle links 8 and a suitable portion of the nut 5 so that the same may be actuated and controlled by the latter. As a convenient means of assembling the parts through the medium of the nut 5, as Well as excluding dust from the adjacent or threaded parts, the compression device preferably comprises a coiled or helical spring 6, surrounding tlie threaded convenient means of compressing the spring 6, as Well as covering and protecting the latter, the compression device is preferably provided with a Ycompression member 6a. In the present instance, the compression member 6a is in the specific form of a cylindrical dust excluding cup having an opening adapted to receive the cylindrical portion 5 loop end 1a,of a' bar up Wear.
